Difference between JavaScript and jQuery

S.No	JavaScript	jQuery
1	Meaning: JavaScript is the most popular scripting language on the internet, and works in all major browsers, such as Internet Explorer, Firefox, Chrome, Opera, and Safari.	Meaning: JQuery is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development.
2	Composed of: JavaScript is a combination of ECMA Script and Document Object Model (DOM).	Composed of: jQuery has Document Object Model (DOM).
3	Web-based application creation: JavaScript has many processes in creating web based applications. Example: Two JavaScript function to change the background color with the onload function that would need to placed into the body tag function changeBackground(color) { document.body.style.background = color; } onload="changeBackground('red');" Note: If we use this unstructured code then there is many problems to validate the html source of web page. So JQuery is best to use and easy to understand.	Web-based application creation: Creating a web based application using jQuery becomes easier. Example: One JQuery changing the background color of a body tag $('body').css('background', '#ccc'); This is the clean code JQuery provides.
4	Animation Creation: Animations are not possible using JavaScript.	Animation Creation: Animations can be easily created using jQuery.
